The latest Google Doodle celebrates the birthday of a woman who helped make computer programming more user friendly.

The late Grace Hopper is credited with several achievements that marked the computer era. As a naval officer during World War II, she was one of the first programmers to tap into Harvard's Mark I computer. After the war, she worked on the UNIVAC, one of the first commercial computers.

But "Grandma COBOL" may best be known for her role in creating the Common Business Oriented Language, which allowed computers to handle words instead of just numbers, creating a revolution in programming.

Hopper also became famous among computer aficionados for the phrase "computer bug." Though the term had already been in use to describe technical glitches, the discovery of a moth in a computer by a member of Hopper's team triggered a surge in its popularity.
